BACKGROUND Ultrasound is a valuable non-invasive tool used in obstetrics and gynecology to monitor the growth and well being of the human fetus. The laboratory mouse has recently emerged as an appropriate model for fetal and perinatal studies because morphogenetic processes in mice exhibit adequate homology to those in humans, and genetic manipulations are relatively simple to perform in mice. ...

Airway branching morphogenesis in utero is essential for optimal postnatal lung function. In the fetus, branching morphogenesis occurs during the pseudoglandular stage (weeks 9-17 of human gestation, embryonic days (E)11.5-16.5 in mouse) in a hypercalcaemic environment (~1.7 in the fetus vs. ~1.1-1.3 mM for an adult). Previously we have shown that fetal hypercalcemia exerts an inhibitory brake ...

Purpose. To study suppressor and/or cytotoxic activity of the nuclear erythroid cells (NEC) against tumor various origins. Material and Methods. C57Bl/6 mice P815, L1210, B16 L929 were used. “Phenylhydrazine” NECs obtained from with induced hemolytic anemia. “Erythropoietin” isolated “phenylhydrazine spleen” further cultured in presence erythropoietin. Another source NEC was neonatal mouse sple...

Background: Several methods for sex selection of embryos have been used in research centers and infertility centers till now. Materials and Methods: In this research, the effect of medium, by placing the mouse (NMRI) spermatozoa in the medium containing certain concentrations of albumin and ascorbic acid, separation of spermatozoa containing X and Y chromosomes and doing in vitro fertilization ...

AIMS The aim of this study was to find an algorithm of better fit for early eye growth than the linear regression usually advanced. METHODS The analysis is based on previously published around term data, the main material being axial ultrasound measurements in preterm (n = 101) and full term infants (n = 25). The postconceptional age of the infants ranged between 36 and 54 weeks. Previously p...

BACKGROUND Developmental dysplasia of the hip is a common disease and treated with various surgical approaches. Improved ilioinguinal (I-I) approach, two-incision Smith-Peterson (TSP) approach, and modified Smith-Peterson (MSP) approach are three main approaches; however, they are rarely compared. The present study compared the operative time, blood loss, intraoperative and postoperative alloge...

Azole agents especially Miconazole are widely used even during pregnancy as antifungal agents. The aim of this study was to assess the usefulness of FTIR Micro-Spectroscopy for discriminating of Miconazole treated liver tissue from control liver tissue. The mice were injected with Miconazole (60 mg/Kg) on gestation day 9 and they were dissected on pregnancy day 15. The fetus fixed, dehydrated, ...

Objective(s): Fetal microchimerism is the persistence of allogeneic cell population that transfer from the fetus to the mother. The aim of this study was to evaluate the presence of fetal microchimerism in the pancreas of the mouse with acute pancreatitis (AP).Materials and Methods: In this experimental study, female wild-type mice were mated with male EGFP+. AP model was obtained by injection ...
